黄莺（Setophaga petechia）使用参考性的“seet”呼叫来警告交配的寄生棕头燕八哥（Molothrus ater）。为了回应白天的鸣叫，雌性莺迅速移动到它们的巢上，这可能会通过物理上阻止雌性燕八哥检查和躺在巢里来防止寄生虫。然而，燕八哥只是在日出前产卵，而不是在白天。我们通过实验测试了雌莺在某天被蚊子的叫声警告后，是否会在第二天日出时（可能发生寄生虫的时候）保持警惕，从而将它们的抗寄生虫反应延伸到未来。正如所预测的那样，白天的seet呼叫回放导致女性莺离开他们的巢不经常在第二天早上，相对于他们的通用反捕食者呼叫和无声的控制回放。因此，参考呼叫不仅传达了当前威胁的身份或类型，而且还引起了未来的警惕，以便在脆弱性增加的时期提供保护免受威胁。
Yellow warblers (Setophaga petechia) use referential ‘seet’ calls to warn mates of brood parasitic brown-headed cowbirds (Molothrus ater). In response to seet calls during the day, female warblers swiftly move to sit tightly on their nests, which may prevent parasitism by physically blocking female cowbirds from inspecting and laying in the nest. However, cowbirds lay their eggs just prior to sunrise, not during daytime. We experimentally tested whether female warblers, warned by seet calls on one day, extend their anti-parasitic responses into the future by engaging in vigilance at sunrise on the next day, when parasitism may occur. As predicted, daytime seet call playbacks caused female warblers to leave their nests less often on the following morning, relative to playbacks of both their generic anti-predator calls and silent controls. Thus, referential calls do not only convey the identity or the type of threat at present but also elicit vigilance in the future to provide protection from threats during periods of heightened vulnerability.
